BENJAMIN L. ROBINSON, OF FLORENCE, INDIANA.

IMPROVEMENT IN PRESSES FOR HAV, COTTON, &c.

Specification forming part of Letters Patent No. 154,191 dated August18, 1874; application filed July 29, 1874.

To all whom it may concern:

Be it known that I, B. L. ROBINSON, of Florence, county of Switzerlandand State of Indiana, have invented certain new and useful Improvementsin Presses, of which the following is a specification:

The nature of my improvement relates to an improvement inbeater-presses, used for baling cotton, hay, and other articles; andconsists in the arrangement and combination of parts which will be morefully set forth hereafter.

Figure l is a side elevation of my press. Fig. 2 is a plan view of thesame.

a represents the body of the press, of any suitable size or form,provided with suitable doors upon its top for inserting the material tobe baled in front of the plunger, and removing it after it is `baled.The plunger c, provided with suitable friction-rollers, is connected tothe jointed levers d e, upon which a heavy weight, g, is placed forforcing the plunger against the material being baled after it has beendrawn back by the operating power. Secured to the levers d, and passingup over the standard z', is a cord or' chain, h, by which the plunger isoperated. The outer end of this cord is tied to a semicircular metalplate, Z, having a projection extending out from its side, and whichmoves around the capstan n, while held in position ingrooves made in thehead and base of the same. Secured to the top of the capstan is thesweep o, to which the motive power is applied, having 4 a pivotedlatch,r,hanging from its under side,

which, as the sweep moves around, catches against the projection s,drawing the semicircular plate to which the rope is attached around withit. As the plate moves around it exerts its pull upon the rope andraises the weight and levers `upward,drawing the plunger back foranother stroke against the bale, until the catch arrives at the trippingdevice t, when it is released from the projection, and the weightimmediately falls, driving the plunger against the bale. As soon as thecatch passes the tripping device it catches against the projectionagain, and thus for every turn of the sweep and capstan the plunger isdriven against the bale. Upon topof the capstan is pivoted a lever, u,having its outer end attached to the catch by a cord, c, so that theplunger can be tripped before the capstan has made a full turn, if ,sodesired. Under the capstan, but independent of it, is placed a drum, w,having notches or recesses made around its top, in which a rod, a',secured to the end of the lever u catches, so as to cause it to revolvewith the sweep. By raising the outer end of the lever the catch r isdrawn outward so as to prevent its engaging with the projection s andoperating the plunger, while the rod a is depressed `so as to catch thedrum, which, as the capstan revolves, turns with it. Fastened to thisdrum is a cord or chain, c', which is secured to the levers d, for thepurpose of drawing them down, so as to hold the plunger braced rigidlyagainst the bale while it is being finished.

The head of the press has two notched arms, e', extending outward fromits rear side,which pass through a cross brace or beam, i', having agroove in its side in which slides a locking device, of any suitablekind, for catching in the notches and holding the head in any desiredposition.

By means of these devices the thickness and size of the bale may beregulated at pleasure.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. The head, having the notched arms e', in combination with a suitablelocking device, for regulating the size of the bale, as described.

2. The plunger c, levers d c, and weight g, in combination with anautomatic operating and tripping device, substantially as set forth.

In testimony that I claim the foregoing as my invention, I hereunto afixmy signature this 25th day of March, 1873.

E. L. ROBINSON.
